Which of the following techniques can be used for the separation of components of a mixture containing two miscible liquids having sufficient difference between their boiling points?

Distillation

The correct answer is option 1. Distillation.

Distillation is used for the separation of components of a mixture containing two miscible liquids that boil without decomposition and have sufficient difference in their boiling points.

To separate a mixture of two or more miscible liquids for which the difference in boiling points is less than 25 K, fractional distillation process is used,
